Wasn’t being defensive. Was just stating fact. There are so many ways to build an AR and even more companies building parts that it is hard to compile a list.
I like mil spec because the designs are battle proven and cheaper. That is my thought. I want something that I could use in combat.
This build will be a beater truck gun. When done I should have about $550 in it. My son will have about $650 in his because he had no parts laying around. This includes Vortex Strikefire 2 optics.
